Jenoptik Laser Diodes

Jenoptik Diode Lasers

Jenoptik produces and develops high-power laser diodes. They range from fiber-coupled laser diode modules, mounted laser diodes / stacks, and semiconductor material. The entire process is covered from wafer to module. Their laser diode products are well established in the industrial, medical, and science industries.

Jenoptik diode lasers are known for their high efficiency and overall reliability. As a result of their laser diode's compact style, they are extraordinarily durable and offer ease of integration with minimal maintenance and zero follow-up costs.

Jenoptik's entire process is manufactured in-house. This allows an oversight of quality control which means the highest possible quality for you plus a long service life. We offer a wide selection of high power diode lasers, but if you need something special, we can develop to meet your specific requirements.

Jenoptik Unmounted Diode Laser Bars:

Outstanding semiconductor material for high-power diode lasers

Product features:

Wavelength: 760 - 1060nm

Output power: 6 - 500W

Operation mode: CW / QCW

Filling factor: - - 75%

Resonator length: 0.6 - 4.0mm

We produce our semiconductor materials under thestrictest quality controls. We work only with state-of-the-art epitaxy, processing, and facet coating technology. Our bars, semi-bars, and single emittersmeet the most exacting demands: They are extremely reliable, efficient and durable.

Our semiconductor products are easily assembled using standard soldering methods. The material supports bothsoft solder (indium) andhard solder(gold/tin). We deliver our laser bars to you with emitter structures separated on the p-side as standard. On request, we can also produce bars with continuous p-side metalization and adapted facet coatings, using low AR coatings for the assembly of external resonators.

Benefits

Economical:Our semiconductors are very efficient and are characterized by a long service life.

Fields of Application

Industry:Semiconductors for high-power diode lasers in direct material processing, for heating or lighting. Semiconductors as pumping sources for fiber and solid-state lasers. Use in printing technology.

Medicine:Esthetics, dermatology and surgery.

Jenoptik laser diodes are well-known as the high-quality industry standard for medical and industrial applications. Jenoptik is an established company which is present in more than 80 countries. Consequently, their diode lasers are known for their high efficiency and reliability. Finally, to ensure the highest possible quality, long service life, with dependable deliveries, Jenoptik manufactures all laser diodes bars in-house.

Jenoptik Mounted Laser Diode Bars:

Bars, Mini-Bars and Single Emitters as Passively Cooled Laser Diodes

Product feature

Wavelength: 808 - 1470nm

Output power: 8 - 300W

Operation mode: CW / QCW

Cooling: actively cooled / passively cooled

Collimation: fast axis / fast axis and slow axis / without

Heatsink: actively cooled / cn / cs

You can choose betweencw and qcw operation. We offerstandard wavelengthsof 808nm, 940nm and 980 nm. On request, we can optimize diode lasers for other wavelengths thanks to the flexibility of our own semiconductor production facility in Berlin. You also receivedifferent emission heights in standardized packages. The collimation is available in Fast-Axis (FA) only or in Fast-Axis (FA/SA).

Our patented CN design means that the bars of our mounted diode lasers arecooled on both sides. This means you can achieve thermal resistances that are very close to those of a microchannel heat sink. Our diode lasers also deliverhigh output power and a low smile.

Jenoptik QCW-Stacks:

Reliable QCW diode laser stacks for the harshest climatic conditions

Product feature

Wavelength: 808 - 940nm

Output power: 270 - 2400W

Operation mode: QCW

Cooling: actively cooled / passively cooled

Collimation: fast axis / without

We assemble our vertical and horizontal stacksusing gold and tin solder (hard solder)as standard. This enables hard-pulse operation underdemanding climatic conditions. Because of theirlightweight construction, the stacks also easily withstand vibrations and shocks. Thanks to theirreliability and efficiency, our diode laser stacks are also used as pumping sources for solid-state lasers, including in the field of high energy research.

As standard, we formpassively cooledvertical stacks consisting up to 16 laser elements or arrange up to 4 laser elements in a row. Other configurations are available upon request. You can thus achieveoutput power up into the kW range.

Benefits

Efficient:High output power up into the kW range.

Compact:Small and lightweight design is easily integrated.

Robust:Shock and vibration resistant.

Reliable:Works even under the most demanding climatic conditions.

High-quality:We only use hard solder.

Fields of Application

High energy research:QCW pumping sources for solid-state lasers.

Medical technology:Long-pulse operation, use in esthetics (epilation) and dermatology.Excitation light source for solid-state lasers in the 1320 nm range for parenchyma surgery.

Defense:Short-pulse operation, use as a pumping source, for lighting or in LIDAR systems.

Industry:Excitation light source for solid-state and fiber lasers.

Jenoptik CW-Stacks:

Vertical stacks to increase output power in CW mode

Product feature

Wavelength: 808 - 980nm

Output power: 128 - 1440W

Operation mode: CW

Cooling: actively cooled / passively cooled

Collimation: fast axis / fast axis and slow axis / without

Our vertical stacks can be used to increase the optical output power of your diode laser. To do so, we stackup to 12 mounted laser bars to form a diode laser stack or an assembly. Each of these laser barsindividually supplies up to 120 wattsin cw mode. Because of the small gaps between the laser bars, you obtainmaximum brilliance from the stacks, enabling you to workhighly effective. You can choose between laser diode stackswith a Fast-Axis (FA) or combined Fast-Axis/Slow-Axis (SA) collimation.

Benefits

Best price/performance ratio:Because of the small gaps between the laser bars.

Powerful:Each of the 12 laser bars individually supplies up to 120 watts in cw mode.

Our fiber-coupled diode laser modules can be used to produce an optical output power of4 W to 400 W in cw mode and 120 W in qcw mode. They are also available infree space format. Depending on their power, these modules are cooled using water, TEC or air.

Because of their reliability and efficiency, our modules are successfully used as beam sources in areas such as solid-state laser pumps, material processing and medicine. They have arobust and compactdesign and have proven their worth in daily use.

We offerstandard wavelengthsof 808 nm, 940 nm and 980 nm. Thefiber core diameterof our diode lasers is 200 µm, 400 µm or 600 µm. On request, we will be happy to adapt the parameters to your individual requirements. You can also choose betweenpilot lasers, monitor diodes and integrated Peltier elements.
